SQL 서버 코드를 Oracle로 변환

Question

SQL Server 코드를 Oracle로 변환하려고했으나 실패했습니다.

다음은 SQL Server의 코드입니다. 누구든지 도와 줄 수 있습니까?

CREATE TABLE [dbo].[DimCustomer] 
(
    CustomerID INT IDENTITY(12,1) NOT NULL, 
    CustomerAccountID VARCHAR(20), 
    FirstName VARCHAR(50), 
    LastName VARCHAR(50), 
    FullName AS CONCAT(FirstName,' ',LastName), 
    ContactNumber VARCHAR(20), 
    EmailAddress VARCHAR(50), 
    MemberShipType VARCHAR(50), 
    MemberShipStartDatekey INT, 
    MemberShipExpiryDateKey INT, 

    CONSTRAINT pk_customer_id PRIMARY KEY (CustomerID) 
) 

Answer 1

(오라클 12C)처럼 간단 :

CREATE TABLE DimCustomer 
(
CustomerID INT GENERATED BY DEFAULT AS IDENTITY NOT NULL --IDENTITY 
,CustomerAccountID VARCHAR2(20)        --VARCHAR2 
,FirstName VARCHAR2(50) 
,LastName VARCHAR2(50) 
,FullName AS (FirstName || ' ' ||LastName)     --calculated column 
,ContactNumber VARCHAR2(20) 
,EmailAddress VARCHAR2(50) 
,MemberShipType VARCHAR2(50) 
,MemeberShipStartDatekey INT 
,MemberShipExpiryDateKey INT 
,CONSTRAINT pk_customer_id PRIMARY KEY (CustomerID)   --comma 
);

순서 및 트리거를 사용하여 대체 : 당신의 question.Your에 버전 별 SQL 서버 태그를 추가

CREATE SEQUENCE DimCustomer_seq START WITH 12 INCREMENT BY 1; 

CREATE OR REPLACE TRIGGER DimCustomer_seq_tr 
BEFORE INSERT ON DimCustomer FOR EACH ROW 
BEGIN 
SELECT DimCustomer_seq.NEXTVAL INTO :NEW.CustomerID FROM DUAL; 
END;
